'PECIFICATION ferming part of Letters Patent NO. 492,030, dated February 21. 1893.

Application filed June 27, 1892. Serial NO. &38,088. (NO model.)

TO all wlwm it may concern:

Be it known that I, ALMERON M. LANE, a citizen of the United States, residing at Meriden, in the county of New Haven and State of Connecticut, have invented a certain new Improvement in Pendulum-Balls, of Which the following is a Specification.

My invention relates to improvements in pendulnm balls, and the Chief Object Of my improvement is to construct a neat and attractive pendulum ball mainly of sheet metal and at a small cost.

In the accompanying drawings, Figure 1 is a front elevation of my pendulum ball. Fig. 2 isa rear elevation of the same, and Fig. 3 is a sectional view thereof On the line OC of Fig. 2. i

I first provide a disk of sheet metal of suitable thickness and perforate it With three holes at equal distances apart and at a uniform distance from the edge. In these holes I secure the same number of shouldered studs 4 and securely I'ivet them in place. I then place this disk of metal in a lathe and preferably hold it therein by a chuck having three holes to receive said shouldered studs, Whereby the disk is heldin place for rotation in the lathe through the medium of said studs. I then bevel Or chanifer the edge Of the disk,

leaving it substantially in the form of the disk 5, in Figs. l and 3. I next blank Out a a disk Of thinner metal With a notch 6 at diametrically opposite points, and I also perforate the same With three hOles at points coincident with the studs 4. The disk is then struck in dies to form the beveled Or dishing shell 7, Or back as shown in Figs. 2 and 3, said shell being' held in place by the shouldered studs 4, the Outer ends Of Which are riveted OI' headed down. The diametrically opposite notches 6 will then form suitable openings for the insertion Of the Ordinary adjusting rod 8 and the pendulmn ball is coniplete. If desired before pntting in the adjnsting rod the pendulum ball may be placed in achnek and its face sinoothed Off and polished.

I claim as niy invention- The herein described pendnlum ball consisting of the disk 5, the shonldered studs secured therein and the beveled Or dishing back Or shell secured in place by said studs, snbstantially as described and for the purpose specified.

ALMERON M. LANE.
